Description

Technical Field

[0001] This utility model relates to the field of glass fiber pipeline technology, and more specifically, to a field quick connection device for glass fiber pipelines. Background Technology

[0002] In the actual construction of power facilities, communication engineering and industrial equipment installation, it is often necessary to make efficient and stable connections for fiberglass pipelines. Especially when the construction period is tight and the installation environment is complex, construction workers urgently need a connection method that can quickly connect and disconnect to improve work efficiency and reduce installation time. However, existing technologies often use traditional methods such as threaded connection or adhesive fixation. These methods are not only cumbersome to operate and inconvenient to disassemble and assemble, but also often require rework if poor connection occurs, which seriously affects the construction progress.

[0003] Furthermore, in applications involving the connection of equipment pipelines, such as systems used to protect cables or transport fluids, the requirements for connection sealing are particularly stringent. Existing connection methods often suffer from poor sealing performance and leakage at the interfaces due to unreasonable structural design or inadequate sealing material performance. This can easily lead to external moisture or dust entering the pipeline, thereby affecting the normal operation of the system. In the long term, these hidden dangers may also result in increased maintenance costs and safety risks. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a quick on-site connection device for fiberglass conduits, which has the following advantages:

[0017] 1. By setting a quick-connect mechanism on the fixed pipe, the quick connection and disassembly between fiberglass pipelines are realized. The quick-connect mechanism uses a sliding block in the sliding hole to cooperate with the slot on the outer wall of the connecting pipe. The sliding block and the limiting structure are driven by the inner contraction spring to ensure that the block can be quickly positioned and reliably locked during the insertion process, thereby significantly improving the connection efficiency, meeting the needs of rapid on-site construction, and avoiding the cumbersome connection steps in the traditional method.

[0018] 2. The locking mechanism is designed with components such as push sleeve, mounting block, arc rod, and rotating sleeve working together to further reinforce the connection after the initial docking. Under the action of the tension spring, the push sleeve can form abutment support for the locking block through the groove. At the same time, the rotating sleeve can lock the entire quick-connect mechanism after being inserted into the arc rod through the support rod, preventing loosening due to vibration or external force during the connection process, and improving the overall safety and reliability of the connection.

[0019] 3. A sealing strip is installed on the outside of the connecting pipe, which works together with the compression spring and sealing gasket on the inner wall of the fixed pipe to ensure the reliability of the seal after insertion. During the insertion process, the sealing strip is pressed against the inner wall under the action of thrust. Combined with the elastic return function of the sealing gasket, it effectively prevents dust, water vapor and other external substances from seeping into the inside of the pipe, thereby ensuring the stability and sealing performance of the system operation and overcoming the shortcomings of poor sealing performance of traditional connection methods.

[0035] A sealing strip 32 is provided on the outside of the connecting pipe 2, and a compression spring 33 is provided on the inside of the fixed pipe 1. Multiple sets of compression springs 33 are provided, and a sealing gasket 34 is provided at the bottom end. This is used to form a good sealing effect when the pipe is connected. The sealing strip 32 and the compression spring 33 are combined to ensure the sealing of the connecting pipe 2 and the fixed pipe 1 and prevent the penetration of external substances.

[0036] The inner wall of the fixed pipe 1 is provided with positioning strips 35, and multiple sets of positioning strips 35 are provided. The outer wall of the connecting pipe 2 is provided with positioning grooves 36, and multiple sets of positioning grooves 36 are provided and slidably connected with multiple sets of positioning strips 35. This is used to ensure that the fixed pipe 1 and the connecting pipe 2 are accurately positioned during the assembly process. The sliding connection between the positioning strips 35 and the positioning grooves 36 provides a convenient positioning method and improves the reliability and stability of the overall structure.

[0037] In this embodiment, during use, the connecting pipe 2 is inserted into the fixed pipe 1, and multiple sets of positioning strips 35 are positioned and inserted into the positioning grooves 36. The rotating control sleeve 21 moves multiple sets of locking blocks 4 into the arc-shaped grooves 22. Multiple sets of contraction springs 6 pull the locking blocks 4 into the locking grooves 5, and push the push sleeve 9 to stretch the tension spring 15. Multiple sets of grooves 25 abut against the bottom surface of the locking blocks 4, pushing the multiple sets of locking blocks 4 to slide along the sliding holes 3, so that the multiple sets of locking blocks 4 abut against the multiple sets of abutment grooves 2. Within 0, multiple sets of locking blocks 4 simultaneously push the connecting pipe 2, causing the sealing strip 32 to be pressed against the inner wall of the fixed pipe 1. The sealing gasket 34 then presses against multiple sets of compression springs 33 and the sealing gasket 34. Then, the rotating sleeve 12 rotates counterclockwise, causing multiple sets of support rods 13 to rotate, allowing multiple sets of insertion holes 14 to be inserted into the arc-shaped rod 11, thereby supporting and limiting the push sleeve 9. Multiple sets of push springs 29 push the limiting block 30 to abut against the limiting groove 31, thus limiting the rotating sleeve 12.

[0038] More specifically, when it is necessary to disconnect, rotate the rotating sleeve 12 clockwise, and push the positioning block to slide into the movable groove 28 through the multiple sets of limiting grooves 31 to squeeze the push spring 29. Then, the multiple sets of insertion holes 14 disengage from the arc-shaped rod 11, releasing the limiting of the push sleeve 9. The tension spring 15 pulls the push sleeve 9 to release the abutment of the multiple sets of locking blocks 4. The multiple sets of compression springs 33 reset and push the sealing gasket 34. The sealing gasket 34 pushes the connecting pipe 2. The connecting pipe 2 drives the multiple sets of locking blocks 4 to slide along the sliding hole 3, so that the multiple sets of locking blocks 4 disengage from the abutment groove 20. Rotate the control sleeve 21 to make the multiple sets of locking blocks 4 disengage from the arc-shaped groove 22. At this time, the bottom of the multiple sets of locking blocks 4 disengages from the locking groove 5, and the connection between the fixing pipe 1 and the connecting pipe 2 is released.

[0039] In summary, during use or operation of the overall equipment: When in use, the connecting pipe 2 is inserted into the fixed pipe 1, and multiple sets of positioning strips 35 are positioned and inserted into the positioning grooves 36. Rotating the control sleeve 21 moves multiple sets of locking blocks 4 into the arc-shaped grooves 22. Multiple sets of contraction springs 6 pull the locking blocks 4 into the locking grooves 5, pushing the push sleeve 9 to stretch the tension springs 15. Multiple sets of grooves 25 abut against the bottom surface of the locking blocks 4, pushing the multiple sets of locking blocks 4 to slide along the sliding holes 3, causing the multiple sets of locking blocks 4 to abut against multiple sets of grooves 25. Within the abutment groove 20, multiple sets of locking blocks 4 simultaneously push the connecting pipe 2, causing the sealing strip 32 to be pressed against the inner wall of the fixed pipe 1. The sealing gasket 34 then presses against multiple sets of compression springs 33 and the sealing gasket 34. Then, the rotating sleeve 12 rotates counterclockwise, causing multiple sets of support rods 13 to rotate, allowing multiple sets of insertion holes 14 to be inserted into the arc-shaped rod 11, thereby supporting and limiting the push sleeve 9. Multiple sets of push springs 29 push the limiting block 30 to abut against the limiting groove 31, thus limiting the rotating sleeve 12.

[0040] When it is necessary to disconnect, rotate the rotating sleeve 12 clockwise. The positioning block is pushed into the movable groove 28 through the multiple sets of limiting grooves 31 to squeeze the push spring 29. Then, the multiple sets of insertion holes 14 are disengaged from the arc rod 11, releasing the limiting of the push sleeve 9. The tension spring 15 pulls the push sleeve 9 to release the abutment of the multiple sets of locking blocks 4. The multiple sets of compression springs 33 reset and push the sealing gasket 34. The sealing gasket 34 pushes the connecting pipe 2. The connecting pipe 2 drives the multiple sets of locking blocks 4 to slide along the sliding hole 3, so that the multiple sets of locking blocks 4 are disengaged from the abutment groove 20. Rotate the control sleeve 21 to make the multiple sets of locking blocks 4 disengage from the arc groove 22. At this time, the bottom of the multiple sets of locking blocks 4 disengages from the locking groove 5, and the connection between the fixing pipe 1 and the connecting pipe 2 is released.
